I have Basecamp and Homeport installed on my computer. I have created and transferred Basechart waypoint and route files from my computer to the Montana and have not had any problems. I also have Homeport and when attached to the Montana (with the G2 Bluechart mini SD installed) the nautical charts in Homeport open and I can create waypoints and routes that can be managed with no problem. When I drag or copy the folder I create on Homeport with the waypoints and routes in it into the Montana or SD card section of Homeport, the data is view-able on Homeport when highlighted where the new folders have been created. The issue I have is that the Montana hand held does not display the waypoint or route data at all. I can see the file in MyComputer/(K)/Garmin/userdata as a .adm file on the SD card when the montana is attached to my computer or I insert the SD card into the reader on my computer but the Montana does not seem to recognize this type of file. Is this a defect or is the Montana made not to recognize this file type. This is problematic because I purchased this very expensive GPS, G2 navigation software and Homeport software to use for navigating on my boat and planning routes on the device is cumbersome.
Thank you
